Two-stage worm gearboxes series SCREAM with a solid shaft at the inlet and version CRMI with a flange mount or an already built-in electric motor from the company STM These are high-quality and reliable transmissions formed by combining single-stage models for various applications and operating modes. A wide range of operating parameters, a model range of a combination of twelve dimensions.
Cast aluminum (for standard sizes 28-85) and cast iron (110-250) are used as the material for the body, aluminum (28-110) and cast iron (130-250) for flanges, high-carbon steel worms, cast iron wheel with a bronze crown, brass sleeve for connection to the motor.
To protect against critical overloads, a built-in torque limiter is provided for this series of gearboxes (in sizes from 28 to 150), which does not make any dimensional changes during installation.
